Dirk quickly crossed the beach and scampered up the barren hill. The rocky ground sliced into his stockinged feet, and he regretted having kicked off his shoes when he swam out of the submersible. The hill rose sharply, and he soon obtained a commanding view of the neighboring coastline.

Looking first to sea, he quickly spotted the Alexandria. She was a small dot in the distance, moored, he guessed, over the site of the sunken submersible. Dirk estimated he would have to hike five miles up the coast to reach a position where the crew might spot him. Gazing inland, he observed a barren range of rolling hills, part of the Cape Sainte Marie Special Reserve. The large national park, created as a wildlife sanctuary, had few resources, save for a handful of hiking trails and campsites.

He shifted his gaze to the east and was surprised to spot a ship two or three miles distant, rising from a tiny inlet. A handful of buildings stood alongside the ship, while a small dredge was moored nearby. Dirk thought of the patrol boat that had rammed their submersible, but he scanned the inlet and saw no sign of it.

Spotting no other signs of civilization, he hurried back to the beach.

“Do you want the good news or the bad news?” he asked Summer, who sat probing the sand mound with a flat piece of driftwood.

“I’m a sunny optimist. Give me the good.”

“The Alexandria hasn’t abandoned us. Unfortunately, they still think we’re aboard the submersible. As far as I can figure, they’re moored over the site where we went down. Plan B says that I hike five or six miles down the beach and try to attract their attention from shore.”

“I missed Plan A.”

“Less than three miles east of here is an inlet complete with a small dock facility and a freighter.”

“And a patrol boat with a bent nose?”

“No patrol boat. I can hike there in under an hour and call the Alexandria. We’ll have you napping in the ship’s decompression chamber in no time.”

“Plan A it is.”

Dirk placed a hand on her shoulder. “You sure you’ll be okay here?”

“Yes, as long as he doesn’t get any ideas about sharing burrows.” She pointed to the old tortoise. The big reptile had traveled less than twenty yards since they awoke, lying on the beach, tossing sand with his flippers.

“He’ll never make it back here in time.”

Dirk turned and moved off down the beach. The morning sun was already baking the sandy terrain, so he followed the shoreline, where the ocean breeze kept it cooler. The growing heat and a dry throat made him crave a drink of water. He knew he was dehydrated, which only added to his lethargy. But Dirk put the thought out of his mind and focused on walking as quickly as his weak legs and shoeless feet permitted.
